Hi Greg,

I'm still having problems getting this running for my student :(

Now I'm having:

java.lang.IllegalAccessError: tried to access field org.gervarro.democles.operation.emf.EMFNativeOperationBuilder.ecorePackage from class org.gervarro.democles.operation.emf.EMFBatchOperationBuilder
    at org.gervarro.democles.operation.emf.EMFBatchOperationBuilder.<init>(EMFBatchOperationBuilder.java:43)

I'm afraid Eclipse also has problems with protected variables (I have no other explanation at this point).

Could you consider adding a public getter perhaps?

Cheers, Tony

anthonyanjorin commented 6 years ago

I'm not sure but perhaps this only works due to package visibility... That would explain why Eclipse is having problems (has nothing to do with protected visibility).

Hi Greg,

any chances of getting this fixed soon? :)

Cheers and thanks, Tony

Hi Tony,

I am terribly sorry for this extreme delay in such an easy case. I already fixed it on my notebook while travelling on the train right after you contacted me. Afterwards, I forgot to do the rest and simply considered the case as completed in my mind. Thanks for the reminder.

The fix is available on the update site.

Bests, Greg

Thanks, Greg. I’ll try it out ASAP :)

Hi Greg,

I'm now getting:

java.lang.IllegalAccessError: tried to access method org.gervarro.democles.runtime.DeltaStore.clearContent()V from class org.gervarro.democles.runtime.HistoryBasedDeltaStore
    at org.gervarro.democles.runtime.HistoryBasedDeltaStore.cleanup(HistoryBasedDeltaStore.java:81)

Cheers, Tony

Fix is available on the update site. Please keep in mind that such an error can unfortunately be fixed in such a trial and error manner. (The runtime OSGi environment might have become more strict in the latest Eclipse version.)

Bests Greg

No problem, Greg. I just hope your deployment process is 100% automated so this ping-pong is not such a pain in the a** for you :) I'll try it out right away.

anthonyanjorin commented 6 years ago

Yay! This seems to be fixed now.
